AUTOMATIC LOOM STOP.

Application led April 17, 1923. Serial No. 632,736.

To all whom i may concern.'

Be it known that l, JAMES K. HArnoori, a citizen of the United States, residing at Danville, in the coun y of Pittsylvania and 5 State of Virginia, have invented a new and useful Automatic Loom Sto a, of which the following is a specification.

This invention relates to automatic stop mechanisms for looms, the primary object of the invention being to provide means acting in conjunction with the usual sand roll of a loom, for actuating the stop mechanism to out off the power to the loom.

Another object of the invention is to provide means which will be automatically operated when the cloth, passing through the loom, becomes tangled on the sand roll.

W ith the foregoing and other objects in view which will appear as the description ao proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 is a vertical sectional view through a loom parts thereof being omitted and disclosing the manner of supporting the mechanism forming the essence of the invention.

Figure 2 is a fragmental elevational view of the same.

Referring to the drawing in detail, the reference character 5 designates the usual sand roll forming a part of a loom construction, and over which the cloth is fed on its au passage to the cloth roll indicated in the present showing by the reference character 6.

A. pair of vertical arms 7 forms a part of the structure, the upper ends thereof being formed with U-shaped bearings 8 to support the cloth rod 9 over which the cloth passes after leaving the sand roll 5.

lThis cloth rod 9 is supported in proximityv to the sand roll 5, so that should the cloth,

which is indicated at 10 tangle, on its passage from the sand roll, the cloth would pile up between the sand roll 5 and cloth rod 9 to move the rod 9 within its bearings. The reference character 11 designates the usual belt shifting rod which is of well known construction and provided with means not shown for shifting the usual power belt from the power pulley to an idle pulley or vice versa. Secured to the rod 11, is an arm indicated at 12 which may be adjusted with respect to the rod 11 to lengthen or shorten the throw thereof.

Formed in the arms 12 at a point adjacent to the free ends thereof, is an opening adapted to accommodate the operating rod 13 which is formed with a transversely eX- tended bar le at its lower end, the bar 14: being designed to contact with the lower edge of the arm 12 so that movement of the rod 13 will result in a movement of the arm 12 to operate the rod 11 and control the movements of the machine.

The upper end of the rod 13 is formed into an eye 15 that embraces a portion of the rod 9 so that movement of the rod 9 results in a movement of the rod 13 to rock the arm 12.

From the foregoing it will be seen that due to the construction of the rod 13 and the manner of supporting the rod 9, upward movement of the rod 9 results in a movement of the rod 13 of arm 12 as described, but it will be understood that this structure in no way restricts the upward movement of the arm 12 to accomplish the purpose of the roll 11 by manually controlled means.

What is claimed as new is :H

1. In combination with the belt shifting rod, sand roll and cloth roll of a loom, vertical arms having U-shaped bearings at their upper ends, a cloth rod supported by the bearings and over which the cloth moves on its passage to the cloth roll, an arm having connection with the belt shifting rod, and a rod connecting the cloth rod and arm. whereby movement of the cloth rod vertically within its bearings, results in a relative movement of the arm to rock the first mentioned rod.

2. In combination with the belt shifting rod Sand roll and cloth roll of a loom, supporting bearings, a cloth rod mounted in the bearings and over which the cloth moves in its passage to the cloth roll, an arm having connection with the belt shifting'rod, said arm having an opening formed adjacent to the free end thereof, a rod having connection with the cloth rod and having its lower end extended through the opening in the arm, said last mentioned rod having a transversely extended bar formed at its free end and engaging under the :mn to move the arm upon Vertical movement of the last mentioned rod, and said cloth vrod adapted to operate to move the last mentioned rod when the cloth passing over the rod becomes tangled.

In testimony that I claim the foregoing JAMES KENEDY HAYDOCK.
